Hello,

Is it possible to remove the HDD in 2017 5K 27" Fusion Drive iMac? Is it true that the HDD and the SSD are separate and not attached together? How would the computer reacts with both Fusion Drive + SSD and no HDD? No need to remove Fusion Drive right?

Also, is it possible to do this upgrade in the 2017 4K 21.5" Fusion Drive iMac?


Thank you

The "Fusion" drive is a logical drive composed of a physical SSD and a physical Hard Disk joined with software. They are not attached to each other as in a hybrid drive. You can use terminal to separate the logical Fusion drive into separate SSD and HardDisk volumes, and doing so will destroy all the data contained on the Fusion volume, so make a backup first. You can also use terminal commands to join a SSD and a Hard Disk into a logical Fusion volume. A Google search will reveal many articles on doing this and any benefits to be gained.

The SSD part is a blade PCI-e drive, and the hard drive bis a 7200rpm platter drive. For mine the best option is (1) a 1TB Flash drive, (2) a 1TB SSD and (3) the Fusion drive. How old is the computer? If within fourteen days and not satisfied take it straight back and exchange for option 1 or 2, at an increased price of course.

Opening your Mac, apart from being difficult, will void the warranty.

(1) 1TB Flash Drive and (2) 1TB SSD are the same thing no?
